A Critical Case Report-Cloacal Malformation: Prenatal Diagnosis and Autopsy Findings

Objective: Cloacal anomalies comprising rare pathological conditions which are observed in female fetuses and must be diagnosed at an early stage of pregnancy. Case Report: An antenatal patient, 23 years old, G3P2L2 was referred to our obstetric service with an ultrasound report of singleton pregnancy of 37 weeks with a septated cystic pelvic mass (7.4cm×7.3cm×8.3cm) in the fetal abdomen at the region of the bladder, atrioventricular septal defect and bilateral renal agenesis with severe oligohydramnios. The patient gave a normal birth with 1.6 kg baby body weight. The newborn had abdominal distension, ambiguous genitalia, and rectal Artesia with a single opening at the perineum. The newborn was placed in the neonatal intensive care unit where further diagnostic investigations were conducted. The neonate died on the 1 st day after 5 hours of life due to respiratory distress. Autopsy and karyotyping were done with proper verbal and written consent of the guardian. Conclusion: In our case, we reported a patient with a cloacal malformation with a cystic pelvic mass, fluid debris was seen on prenatal ultrasound which septate representing hydrocolpos of duplicating vagina. Thus, meconium and vaginal secretions accumulate in the compliant structure of vagina causing hydrocolpos which are rare condition rather than fetal ascites. Ultrasound with differential diagnosis at the early gestational stage can make a huge difference in decreasing such anomalies and early stage fetal mortalities.
